Looked at the Chatterbox Client, and I assunme that this is the sub you are talking about:

######################################################################

#
# closeDOSParent
#
# Closes the dos prompt that created this process
#
sub closeDOSParent {
    # This just simply doesn't work.  I'm not sure why.
    return;
    return if ($opt_debug); # debugging info goes to STDOUT!
    if ($^O =~ /MSWin32/i) {
    my($process);
    my($program) = $^X;
    $orig_params =~ s/\-c\S*\b//g;
    my($pgm) = "perl $0 $orig_params";
    eval '
        use Win32::Process;
      Win32::Process::Create($process,"$program","$pgm",0,DETACHED_PRO
+CESS,".") ||
          die Win32::FormatMessage(Win32::GetLastError()) . "\n";
    ';
    exit;
    }
}

I'm not looking to close the DOS window that started my process, but trying to avoid the console windows popping up when doing an "rsh" from the program. They close again immediately, but having 6-7 windows popping into the foreground evey minute is a pain.

I'll look into the Win32::Process docs and see if I can figure out anything....

Another thought I just had while waiting for the pizza delivery man was "Can you daemon-ize it?" ... maybe Win32::Daemon is an approach, pass the service instructions, then kill the service when the app closes?

I have no real idea if this will even work, but my blood sugar is low ...

All this command does is hide the DOS window that $pgm is spawning (so launch rsh with that type of command). Look around on the site, there have been many other questions WRT the same thing, including my own - I have used this solution and it works.
